HYDROCARBON-BURNER.

Specification of Letters Patent.

Patented May 17, 1910.

To all whom it may concern:

Be it known that we, THOMAS H. CLARK and J OSEPH H. NEQUETTE, both citizens of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

Our invention relates to burners of the vapor generating type, and more particularly to that class adapted to continually convert hydrocarbon distillates into a full gas or vapor and consume the same, and one of the main objects of our invention is to provide a novel means for removing the burner generator for cleansing purposes.

A further and important object is to provide a novel operating mechanism for the needle valve, thereby enabling us to so place the valve in relation to the generator that it will continually generate gas of a good quality in the chamber regardless of the intensity of the burner flame.

Generating chambers in burners of the above mentioned type frequently become clogged with the unconverted waste products of the fuel that is used, such as carbon, tar, etc., thus necessitating a frequent cleansing of the chamber before the burner will operate at its maximum capacity, and as these chambers are usually constructed it is impossible to readily remove them without subjecting the operator to considerable inconvenience. By means of our novel construction and placement of the generating chamber, it may be instantly removed from its position and replaced again after cleansing with little or no trouble.

We accomplish the above objects by means of the device described herein and illustrated in the accompanying drawings, in which Figure 1, is a side elevation of our com plete burner partly in section showing its method of placement in a stove. Fig. 2, is a sectional plan view taken on line 22 of Fig. 1. Fig. 3, is a cross sectional detail of the burner taken on line 33 of Fig. 1.

Referring more particularly to the drawings 5 designates an oil supply pipe designed to be connected to an oil supply tank (not shown), which is preferably placed so as to feed the oil to the burner by gravity. Supply pipe 5 is preferably provided at the top thereof with an angle inlet valve 6 of any well known type. Connected to outlet 7 of this valve is an oil inlet pipe 8 which leads to an oil reservoir 9 which contains a packing 10, preferably gravel, to absorb the impurities contained in the oil before it reaches the generating or retort chamber 11. Reservoir 9 also performs the function of slightly warming the oil before delivery to the generating chamber, thus maintaining the oil in a condition for instant conversion into a gas.

Generating chamber 11 is preferably comprised of a pipe of approximately the same diameter as inlet pipe 8, and is provided with tapered ends 12, which are adapted to form gas tight joints when inserted in tapered seats 13 and 14 formed in nipples 15 and 16, respectively.

Operatively mounted on inlet pipe 8 is a generator removing means 17 which preferably consists of a short nipple 18 externally threaded on both ends and threaded internally as at 19 for the reception of the externally threaded end of pipe 8, the other end of this pipe is rigidly secured to inlet of reservoir 9. The end of nipple 18 opposite the internally threaded end is provided with a stuffing box 20 of usual construction.

By the provision of the generator removing mechanism we are enabled by means of an operating handle 22 rigidly secured to pipe 8 to instantly remove the generator for the purpose of cleansing, a few turns of handle 22 rotating pipe 8 into the internally threaded end of nipple 18 a sufiicient distance for the removal of the generator.

The threaded end of nipple 16 is connect ed to a downwardly extending elbow 23, which is connected to a tie 24, by a COIlIGCtin i e 25, a as su p y pipe 26 leaing thzrdfsom to a burner tip 27 which will be described fully hereinafter.

The burner mechanism is preferably supported in place in the stove firebox 28, whose front wall is provided with a door 29, by means of a threaded rod 30 and an adjusting plate 31. Rod 30 passes through an aperture 32 formed in door 29 and engages burner tip 27 a nut 33 engaging the free threaded end of rod 30 and bearing against the outer face of door 29. The lower end of plate 31 contacts with the inner face of the stove door and its upper end is preferably provided with a pair of adjusting screws 34, which maintain the burner in a horizontal position with respect to the bot tom of the firebox.

. Burner tip 27 is preferably formed of steel or other suitable metal and is preferably rectangular in configuration as illustrated. This tip is provided with a vertically disposed bore 85, the lower end of which is closed by a screw plug 36, its upper end terminating in a conical shaped outlet orifice 37, in which a conical valve stopper 38 is adapted to seat. The lower end of stopper 38 is provided with a rack 39 which is engaged by a pinion 40 formed on the inner end of an operating rod 4-1, a knurled thumb nut 42 providing a simple means of rotation. Rod 41 passes through a stufiing boX 43 secured in burner tip 27.

It will be at once apparent that by the novel construction of the burner valve operating mechanism we are enabled to place the burner tip 27 directly under the generating or gas retort chamber 11 so that the flame issuing from the orifice will impinge directly at right angles and in close proximity to the retort chamber, which is essential when operating the burner at its minimum capacity.

By the employment of a needle valve designed to be operated on rack and pinion principle, the valve may be placed so close to the generating chamber that when operating at its lowest capacity the flame will furnish enough heat to instantly convert the oil into a perfectly combustible gas, that will not emit smoke or soot when ignited.

Secured to the lower end of tee 2a is a starting pan 4-1 which is supplied with oil from a small pipe 45 secured to pipe 5 and controlled by valve &6.

In the operation of our burner, valve 2L6 is first opened to supply a small quantity of fluid to the starting pan 44. As soon as the generating chamber has been sufficiently heated (which it will be in a few moments) the flame deflector d7 having been turned to its desired position, valve 6 is opened to a slight extent so as to admit a restricted flow to reservoir 9 and from thence to the generator 11. As the generator becomes highly heated the flow of oil is increased until the generator is operating to its fullest capacity. The admission of gas from the chamber through the burner orifice being at the same time controlled by means of the conical stopper 38.

It will be observed by the foregoing description that we have provided a burner by means of which we are enabled to control the intensity of the flame, and at the same time provide a burner whose generating chamber may be freed of impurities with the minimum expenditure of time and labor.

It will be further observed that our burner may be used with general satisfaction in dif-' ferent situations giving equally as good reber detachably connected to said oil warm ing reservoir, and means secured to said oil supply pipe for maintaining the generating chamber in detachable relation to the warming reservoir.

2. A hydrocarbon burner, comprising an oil supply pipe, a gas retort detachably secured in frictional engagement with said supply pipe, a mechanism mounted on said supply pipe for maintaining the said retort in frictional gas tight relation to said supply pipe, said mechanism also providing means whereby said retort may be disconnected from said supply pipe, and a burner leading from said retort.

3. A hydrocarbon burner, comprising an oil supply pipe, a gas retort detachably secured in frictional engagement with said supply pipe, a mechanism mounted on said oil supply pipe for maintaining the said retort in gas tight relation to said supply pipe, said mechanism also providing a means whereby said retort may be disconnected from said supply pipe, a burner leading from said retort, and means to control the volume of gas issuing from said burner.

4. A hydrocarbon burner, comprising a gas retort, an oil supply pipe leading to said retort and being held in detachable and frictional engagement therewith, a mechanism mount-ed on said supply pipe for maintaining the supply pipe in frictional gas tight relation to said retort, and a burner tip connected to said retort.

In witness that we claim the foregoing we have hereunto subscribed our names this 10th day of October, 1908.
